Seoul Semiconductor announces production dates for DC-driven Acriche 

At this week’s Lightfair International event (LFI 2011) in Philadelphia, PA, USA (17–19 May), South Korean LED maker Seoul Semiconductor (SSC) is announcing the latest extension of its Acriche product family.

Unlike other devices in the family, the new DC-driven Acriche will be optimized for DC operation and still be able to operate on AC power like the traditional Acriche products. Performance will reach 140 lumens and 120 lm/watt when the part is released to mass production in the June time frame. By the end of the year, performance is expected to reach 170lm and 150lm/W.

The new product is classified as a 1 Watt part but will run on only 20mA DC current at 55V in order to improve overall system efficacy at the fixture level. Higher-voltage operation allows the fixture designer to choose more efficient AC-to-DC power supply options to hold the fixture efficacy higher than could be used for traditional low-voltage LEDs, says the firm. The product can still operate from an AC supply, giving the designer flexibility to use the same product in a variety of applications or situations, especially in space-conscious applications where a converter may not fit.

Seoul Semiconductor says that the new product takes advantage of its patented Acriche intellectual proprietary. The particular technology is just one of more than 300 patents held by Seoul Semiconductor and its subsidiary Seoul Opto Device in the AC LED marketplace. The firm reckons that optimizing for DC operation makes the array desirable for applications where AC power may not be available, such as renewable energy sources like solar power (which produces DC current).
